HORSESHOE-NAIL MACHINE-M SPECIFICATION forming part of Letters PatentNo. 304,248, dated August 26, 1884-.

Application filed August 9, 1883. (No model.) I

To all whom itmay concern:

Be it known that we, Asa N. W'HEELER and J OHN L. PATCH, citizens of theUnited States, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Improvement in Machinesfor Making Horseshoe-Nails, of which the following is a specification.

The object of our invention is to combine IO in one machine therolling-machine and trimming-machine now usually employed in themanufacture of horseshoe-nails, therebydispensing with a large amount ofmanual labor.

The invention consists in mounting the die rollers on a frameimmediately over the die of the trimmer, and in providing a conductorbetween the two, so that as a nail-blank passes from'the die-rollersto'be trimmed it shall be so guided as to beheld in the proper positionfor the punch to strike it and force it through the die, thisbeing'accomplished by the head of the nail falling into a fork orpocket, after which the nail is caught and held by a pair of nippersoperated by a suitable cam. Then a slide which covers the lower portionof the conductor is withdrawn by a suitable cam, and the punch is freeto operate upon the nail -blank so held.

Referring to the accompanying drawings, Figure 1 represents a front viewof a machine embodying my invention. Fig. 2 is a horizontal sectiontaken on line X X of Fig. 1. Fig. 8 is a vertical section taken on lineY Y of Fig. 2. Fig. 4 is a view of the face of the die, showing the forkor pocket attached. Fig. 5 is a face view of the scrap-clearer.

A is the frame of the machine, on the top of which are mounted thedie-rollers B B and trough Qfor holding the nail-blanks, which trough isalso provided with a conductor, 0, for feeding the blanks to therollers.

D is a die-carrier secured to the inner side of the frame A, and E is apunch-holder free 5 to slide in guides F F, secured to the front of theframe A.

The die-rol1ers B B and the punch-holder E are both driven from the mainshaft G, which has its bearings in the frame A. On one end of the shaftG is mounted a driving-pulley, H,

tion to the die-rollers B B.

held in the carrier D, is placed a conductor,

and clutch-collar I, forjthrowing the machine in and out of gear; also,a cog-wheel, J, that gears with another cogwheel, K, which latter gearswith a cog-wheel, L, that imparts mo- The opposite end of the shaft G isturned down so as to form an eccentric to impart'a reciprocating motionto the punch-holder E.

Between the die-rollers B B and the die d, 6

o M, which is closed on all four" sides down as far as the-top of thedie (Z, andffrom there down on'the two sides only, the die forming theback of the conductor, and asliding 'c'over, N, forming-the front; Thecover N is "sup ported inguides P,--a-nd is-' operated from a cam, B,through rod Q, in such manner that when the punch has advanced so as tonearly touch the cover the latter will be withdrawn and held out of theway until the punch has 10 completed its stroke and receded, so as to beclear of the cover N, which is then again pushed over the opening in theconductor.

Secured to the bottom of the die d is a pocket, a, (see Fig. 4,) intowhich the head of the nail falls after passing through the coniductor M.By means of this pocket the nail is caused to always stand in its properposition in relation to the die, thereby preventing much waste, as thenails cannot get askew, and so be improperlytrimmed.

S S are a pair of nippers, pivoted at or about their centers to thedie-carrier D. The lower ends of these nippers are provided with pinse,that pass through converging slots ff in a sliding plate, that is pushedin and drawn out by an arm, h, secured to a spindle, 9', provided at thetop with an arm, Z, that is operated from a cam, B, through rod on. Asthe plate 9 is pushed in, it expands the lower ends of the nippers, andconsequently the upper ends are drawn together and hold the nail thathas fallen into the pocket a in an upright position when the cover N isdrawn back, and their motion is so timed that they will release the nailas soon as the punch has advanced to touch the same.

The cams R B are mounted onthe shaft carrying the cog-wheel K, whichshaft is carried in a bearing, A, on the frame A. The I00 cams are sosecured to the shaft that they can be easily taken off and replaced byanother set, according to the number of nails it is required to turn outin a given time.

T is a scrap-clearer (see Figs. 1 and 5) carried on the end of a rod, t,which is held loosely in a hole in the punch-carrier E, the said holebeing of such a depth as to allow the punch F to advance in front of theclearer T, and as the punch is withdrawn from the die with the scrapupon it the clearer is pushed back by the scrap until the clearer comesagainst a stop, U, and, the punch sti l receding, the scrap is forcedoff. The stop U is made adjustable, and is carried'by the bracket V.

The operation is as follows: The machine being set in motion, anail-blank is fed into the conductor 0, and, passing between thedierollers B B, is pressed into shape in the ordinary manner. It thenpasses down the conductor M, and the head falls into the pocket a. Thecam R now operates the sliding plate 9, and the nippers S S close uponthe nail just above the head. In the meantime the punch has beenadvancing toward the die and nearly touches the cover N, which latter isnow withdrawn by the cam R, and the nippers at the same time releasingtheir hold of the nail. The punch, finishing its stroke, forces the nailthrough the die and recedes with the scrap upon it, which is pushed offby the clearer as soon as the latter touches the stop U. As soon as thepunch is withdrawn sufficiently, the cover N is again pushed over theopening, and the conductor M is ready to receive another nail.

What we claim as our invention is 1. In a horseshoe-nail machine, thesliding cover N, operated by means of the cam R, in combination with theconductor M, thepocket a, and nippers S, substantially as and for thepurpose set forth.

2. In a horeshoe-nail machine, the pocket (1,

in combination with the die (1 and conductor M, substantially as shownand described.

3. In a horseshoe-nail machine, the nippers S S, in combination with thepocket a, die d,

and conductor M, substantially as shown and described.

4. In a horseshoe-nail machine, the plate g, provided with convergingslots ff, for operatingthe nippers S S, in combination with the arm h,spindle j, arm Z, rod m, and cam R, substantially as shown anddescribed.

5. The combination of the carrier E, the rod t, the clearer T, theadjustable stop U, and the unch F, as and for the purpose set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
